Epic announced today a move that makes the Unreal Engine development kit available to all, at only $19 per month. In a risky move to counter other 3D engines in the mobile space, Unreal Engine 4, launched today, is available to anyone that wants to pay the $19 per month fee. That engine can be used to deny games to both desktop and mobile games. Previously the engine that powers Infinity Blade would cost millions and require a negotiated deal.

Unreal dies require that developers that make money from games developed with The engine, from premium, free to play, or ad supported, to pay a 5% gross license fee.
